Fundamental Study on the Media Ecology in the 21th Century Information Society

为了探究多渠道信息环境下当地信息媒体的实际使用情况，我们对Yonago市819名20-69岁的市民进行了社会调查。我们询问了受访者对电视、报纸、有线电视和其他当地媒体的接触情况以及对互联网的使用情况。我们还对初海有线电视台公共频道的服务员进行了小组采访。我们还继续进行了Keitai交流的对话分析，基于大约10名学生的对话记录和电子邮件交流。通过调查研究，我们得到了以下证据。(1)来自电视和互联网的使用和满足的结构有些相似，在功能上是可替代的。(2)用户订阅有线电视的最强烈动机是多频道环境和专业节目，对多频道电视的需求强烈。(3)初海电视台社区频道深受观众欢迎。当地以事件为导向的节目，如地震新闻、选举投票率报告、年度社区节日等，尤其受欢迎。(4)虽然公共通道的收视率较低，但很多人都有过接受初凯电视台本地节目采访或接触的经历，对社区发展起到了积极的作用。通过对Keitai语音对话和电子邮件的会话分析，发现各种各样的面部标记或图标被用来表达情感。研究还发现，通过开台通信的电子邮件信息简短、随意，且在短时间内移动频繁，体现了移动传播媒介的特点。
